Hi Malo, BTW: This problem is not really ELDK related. We might consider moving this discussion to the linuxppc-dev list.

I made the following: > $ make ARCH=ppc > CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/power > pc-linux/powerpc-linux- make 44x/sam440ep_defconfig OK, from your next mail, we already know that "ARCH=powerpc" is correct. But why did you use 44x/sam440ep_defconfig? You should use "ppc44x_defconfig" instead. No need to add Yosemite with "make menuconfig" after that. > $ make ARCH=ppc > CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/power > pc-linux/powerpc-linux- make menuconfig > Here I selected yosemite board at the platform support option, and > enabled the early debug UART physical address minor part 0xef600300: > and major: 0x8 (as it was specified in the yosemite.dts) at the kernel > hacking option, the I compiled the kernel, loaded it in the yosemite > board, and got the following log: > CPU clock-frequency <- 0x1fca0550 (533MHz) > CPU timebase-frequency <- 0x1fca0550 (533MHz) > /plb: clock-frequency <- 7f28154 (133MHz) > /plb/opb: clock-frequency <- 3f940aa (67MHz) > /plb/opb/ebc: clock-frequency <- 3f940aa (67MHz) > /plb/opb/serial@ef600300: clock-frequency <- a8c000 (11MHz) > /plb/opb/serial@ef600400: clock-frequency <- a8c000 (11MHz) > /plb/opb/serial@ef600500: clock-frequency <- a8c000 (11MHz) > /plb/opb/serial@ef600600: clock-frequency <- a8c000 (11MHz) > Memory <- <0x0 0x0 0xffff000> (255MB) > ethernet0: local-mac-address <- 00:10:ec:00:90:10 > ethernet1: local-mac-address <- 00:10:ec:80:90:12 > > zImage starting: loaded at 0x00400000 (sp: 0x0fe2fb60) > Allocating 0x419198 bytes for kernel ... > gunzipping (0x00000000 <- 0x0040e000:0x007236e4)...done 0x305060 bytes > > Linux/PowerPC load: root=/dev/nfs rw > nfsroot=192.168.57.2:/opt/eldk-5.0/powerpc/powerpcrfs > ip=192.168.124.112::192.168.124.1::eolophua:eth0:off > console=ttyS0,115200 > Finalizing device tree... flat tree at 0x730160 > > It is all. No loading is forward anyway. So, my quiestions are following: > * How to enable the debgu after the kernel went to "kenry" function? > * What problem may stop loading the kernel? Not really sure whats going wrong here. I'll try to test it on my Yosemite soon. Which kernel version did you use (git tag, or commit ID)?
